Snowpack Summary
The 10 - 15 cm of new snow from the last few days has been redistributed into firm wind slabs at higher elevations. In isolated areas at treeline and below new snow is buried a layer of small surface hoar and facets. This layer has not shown recent signs of instability.
A faceting crust from mid-November can be found down 60 cm within the midpack and is reportedly bonding well.
In general the snowpack is highly wind effected which has resulted in a wide variation in snowpack depths. Depths at treeline range from 50 to 125cm.
